I liave seen specimens only from tlie Port Lincoln district ; 

 ihej were dug up from under the soil near the roots of a 

 Eucalyptus. 



CAYOi^IJS. 



'Oavonus Sharpi, sp. nov. Supra nigerrimus ; nitidus ; subtus 

 sat dense longe fulvo-pubescens ; elytris obscure punctu- 

 lato-substriatis, apice Isevigatis. Long., 8 1. Lat., 5 1. ('vix). 



Mas. Prothorace disco antice excavato, margine anteriore 

 in cornu brevi producto. 



Pem. Latet. 



Clypeus deflexed, rounded in front ; it and the head roughly 

 and closely punctured ; an obscure transverse keel runs across 

 the middle of the vertex, between which and the basal keel of 

 the clypeus the forehead is feebly concave. The prothorax is 

 about half again as wide as the distance from its base to the 

 apex of the horn ; the sides are moderately rounded, the base 

 scarcely bisinuate and about twice as wide as the front margin. 

 The excavation occupies the anterior three-quarters of the disc 

 and its surface is coarsely and somewhat reticulately wrinkled ; 

 its sides are not elevated. The frontal horn of the thorax, 

 viewed from the side, rises above the head nearly as much as 

 the length of the clypeus ; it is inclined forwards and a little 

 turned up at the end, which is blunt. The scutellum bears a 

 few scattered punctures. The elytra can scarcely be called 

 " striate." They are marked with rows of punctures which do 

 not nearly reach the apex, but hardly fail in front (except 

 absolutely on the humeral callus). The pygidium is not very 

 nitid, its puncturation well defined about the base but be- 

 coming feebler hindward. Differs from C. armatus, Sharp, in 

 the presence of a frontal keel, in the shorter anterior horn of 

 the prothorax, and in the absence of horn-like elevations of 

 the sides of the excavation ; also in the less indication of 

 strise on the elytra, and the greater regularity of the rows of 

 punctures on the same. The elytra also are not quite so short 

 in comparison with the prothorax. 



A single specimen occurred at Port Lincoln. 

 C. sculpt urai us, sp. nov. Supra nigerrimus ; sat nitidus ; sub- 

 tus sat dense longe fulvo-pubescens ; elytris fortiter sat 

 sequaliter punctulato-striatis. Clypeo postice fortiter 

 elevato-carinato. Long., 9 1. Lat., 5 1. 



Mas. Prothorace disco antice excavato, margine anteriore in 

 cornu sat elongate producto. 



Pem. Latet. 



The general resemblance of this species to the preceding and 

 to C. arinatus, Shp., is so close that it will save useless repeti-
